Congress has dodged a government shutdown, agreeing to a $1 trillion spending bill that features a variety of rare compromises. Both Democrats and Republicans won some concessions, and it's too early to say who came out on ...

Alternative lighting is emerging as a potent method to combat the energy crisis. Light-emitting diode (LED) lighting technologies could provide an innovative way to save energy and make wasteful lighting obsolete.

Once broken, a compact fluorescent light bulb continuously releases mercury vapor into the air for weeks to months, and the total amount can exceed safe human exposure levels in a poorly ventilated room, according ...

When semiconductor nanorods are exposed to light, they blink in a seemingly random pattern. By clustering nanorods together, physicists at the University of Pennsylvania have shown that their combined "on" time is increased ...

In a new study, EMPA researchers have investigated the ecobalances of various household light sources. In doing so not only did they take into account energy consumption, but also the manufacture and disposal processes. They ...

(PhysOrg.com) -- RTI International has developed a revolutionary lighting technology that is more energy efficient than the common incandescent light bulb and does not contain mercury, making it environmentally ...

(PhysOrg.com) -- While compact fluorescent lights (CFLs) are currently the primary alternative to incandescent light bulbs, a company from Seattle predicts that its own novel light bulbs will eventually replace ...

(PhysOrg.com) -- Scientists have developed a lighting device that can change its color temperature throughout the day, matching the natural daylight chromaticities produced by the sun. Currently, no other ...

German scientists said Wednesday they had tweaked organic light-emitting diodes (OLEDs) -- the materials used in flat-screen TVs, laptop computer screens and mobile phone displays -- to become flexible, energy-efficient ...

(AP) -- Light-emitting diodes are prime candidates for replacing inefficient incandescent bulbs, but have a few things working against them. They can provide a pleasing warm light or they can be energy-efficient, ...
